Problems with Dependencies and Classpath
Hi,
currently i am trying to get my Java program running outside of the
Netbeans IDE. Within Netbeans, it works well, all dependencies are
correctly loaded and executed.
But if i try to run the program from the console with java -cp or java
-jar, i get NoClassFoundDefError concerning the dependencies of the
project.
My pom.xml uses
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>...omitted...</mainClass>
<addClasspath>true</addClasspath>
</manifest>
</archive>
</configuration>
</plugin>
as buildoptions
Any ideas concerning this issue? Most likely, sth. with the classpath is
wrong, but i can't figure it out.
Best regards and thank you,
Matthias

Hello,
tank you for the fast and many replies!!
works fine now.
Maybe it would be useful to integrate this issue in the maven "Getting
started" documentation.
Best regards,
Matthias

- Use the plugin dependencies to obtain all required jar (for example put it in target/lib)
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
- then in jar plugin tells it to use your prefix
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>...omitted...</mainClass>
<addClasspath>true</addClasspath>
<classpathPrefix>./lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
Then you can launch your application via java -jar tar/XXX.jar
Works fine for us :) hope it will help you.

Hello Matthias,
Read this:
http://maven.apache.org/plugins/maven-assembly-plugin/usage.html
You can use
mvn assembly:assembly
To get a jar with all dependencies.

Shanbo

this willl just generate the relevant manifest entry, but will not ensure
that the jars are at the designated location at runtime. To get them there,
you could use the maven-assembly plugin, or you could merge all dependency
jars into the main jar using the maven-shade-plugin.
